Ok bear with me as this is a long one. I have a 360 and the big remote. In the same room I have a HTPC with IRman and Girder and I also have a Harmony 525 programmable remote. I want to control my PC with the HArmony but need to set up a template remote to control it. I know the 360 remote can control both the 360 and an MCE. So I want to first setup girder by learning the media 360 remote buttons and then I will map the same buttons to the harmopny. My harmony already can control the 360. But as I don't have an MCE i'm n ot 100% sure on how it works. ie if I did have an MCE and I pressed On on the remote wouldn't it turn both the 360 and the MCE on, ie wouldn't the devices get a bit mixed up or is there some way of switching the remote a bit like you do with a standard all in one programmable remote? Thanks for any help.
